Mount Olympus is the highest mountain of Washington's Olympic range. It is a massive glacier-clad mountain with three peaks, rising above the rainforests near the Pacific coast. The West Peak is the higher of the three, though only slightly higher than the Middle Peak (7,930 ft.) and East Peak (7,780 ft.). These are three of the four highest peaks in the entire Olympic Range, and together rise impressively above the surrounding mountain landscape.

On July 4, 1788, British Captain John Meares named Mount Olympus which had been called El Cerro de la Santa Rosalia by Spanish explorers.
